I met THE top guy of CFD of Ferrari-F1 and I can tell you he isn't a monkey running code thrown at him. I asked him how he landed what in my opinion is just about the most cutting edge job that exists. He learned the ins and outs of aerodynamics and numerical methods. He didn't learn how to just use them, he completely understood them.
If you guys want to really know CFD, get Matlab or some equivalent and start writing simplified 2d solvers, even 1D. Start eliminating simplifying assumptions (If you've seen my website, you've seen how many simplifying newb like assumptions I make) used in your model. Work on increasing convergence, estimating boundary conditions, learn the nitty gritty numerical methods and in his words "Keep fighting"
I might have to just start a thread for that, as this may be detracting from the oringinal topic which was Russ and I and a few others just running code we didn't really understand.
By the way, if anyone knows how to get ahold of Russ please let me know. Thanks, and hope this post helps.
